That's cute. You can make all sorts of origami to use as earrings. Some people at craft fairs actually do that, and they charge something like $4 for some strips of solid paper + star instructions - but if you like origami, I say invest in a good guillotine paper cutter and go crazy!

MissNoemi - there's a video of how to do it at http://www.foldastar.com/, just scroll down the page a little bit. You can also google origami star for step-by-step instructions if you prefer those instead.
